Thanks for your reply. The mod I had originally tried without success was to find instances of:
Code:
"product" => "{product_name}-p-{productid}.html",
in html_catalog.php and change them to something like:
Code:
"product" => "{product_name}-p-{productcode}.html",
This doesn't work, so I was wondering how to call the productcode value in this script?[/code]
